Quick Connect Capture Plates are designed to work with popular king pin box models simplifying and significantly reducing installation times. Most Quick Connect applications slip over the king pin and are held in place by a set screw and nylon spacer, holding it onto the king pin box. When the trailer is hooked up to the hitch, the Capture Plate's wedge isolates the king pin from turning in the fifth wheel plate, causing the Cam Assembly to activate and allowing the Super Glide to move as turns are being made. Quick Connect Capture Plate #331760 is designed to fit most 13-5/8" wide 5th Airborne/Rota-Flex/Road Armor pin box models.
